James Bardin 1756b3d09f ProviderConfig needs an Inherited flag

James Bardin 0afd4a9097 Lookup registry module versions during Tree.Load.
Registry modules can't be handled directly by the getter.Storage
implementation, which doesn't know how to handle versions. First see if
we have a matching module stored that satisfies our constraints. If
not, and we're getting or updating, we can look it up in the registry.

This essentially takes the place of a "registry detector" for go-getter,
but required the intermediate step of resolving the version dependency.

This also starts breaking up the huge Tree.Load method into more
manageable parts. It was sorely needed, as indicated by the difficulty
encountered in this refactor. There's still a lot that can be done to
improve this, but at least there are now a few easier to read methods
when we come back to it.

James Bardin 0d10564a74 remove the registryDetector
The detection of registry modules will have to happen in mutliple
phases. The go-getter interface requires that the detector return the
final URL, while we won't know that until we verify which version we
need. This leaves the regisry sources broken, to be re-integrated in a
following commit.

James Bardin ee36cf28e0 a series of test commits
wire up HTTP so we can test the mock discovery service

test lookupModuleVersions

Add a versions endpoint to the mock registry, and use that to verify the
lookupModuleVersions behavior.

lookupModuleVersions takes a Disco as the argument so a custom Transport
can be injected, and uses that transport for its own client if it set.

test looking up modules with default registry

Add registry.terrform.io to the hostname that the mock registry resolves
to localhost.

ACC test looking up module versions

Lookup a basic module for the available version in the default registry.

James Bardin c01dfa7757 failing test for changing intermediate modules
This test highlights how changing an intermediate source path prevents
reloading of submodules. While this is somewhat of an edge case now, it
becomes quite common in the cacse where module versions are updated.

James Bardin a5c86aeff6 Use the new regsrc and response packages
Adds basic detector for registry module source strings. While this isn't
a thorough validation, this will eliminate anything that is definitely
not a registry module, and split out our host and module id strings.

lookupModuleVersions interrogates the registry for the available
versions of a particular module and the tree of dependencies.
2017-10-27 09:08:15 -04:00
James Bardin 0bc279557e add more metadata to the Tree and the storage path
Submodules were located by using their module path as the storage key.
Now that modules may have versions, a submodule needs to know how to
locate the corect source depending on the versions of its ancestors in
the tree.

Add a version field to each Tree, and a pointer back to the parent Tree
to step back through the ancestors. The new versionedPathKey method uses
this information to build a unique key for each module, dependent on the
ancestor versions.

Not only do stored modules need to know their version if it exists, but
any relative source needs to know all the ancestor versions in order to
resolve correctly.

James Bardin 7416e7a6e0 update the module manifest implementation
The getter.Storage abstraction is proving entirely inadequate here, but
we can't replace it wholesale at the moment.

The Tree loader needs to know the location of the manifest before it can
start loading any modules. Since the version will have to be part of the
hashed storage key, there is no way to know what version of each module
are stored. The storageDir function will extract the StorageDir field
from the underlying FolderStorage instance for the tree to locate the
manifest.
2017-10-27 09:08:15 -04:00
James Bardin 283d88551a Add a new module storage manifest
To add registry support, a workaround in the local module storage was
added to record the subdirectory containing the module source from
within the archive file. Here we replace that temporary implementation
with the full manifest needed to record the necessary module metadata
for module loading.

In order to support versioned modules, the actual stored version needs
to be recorded. This can't be derived from the configuration, because
the configuration only contains the constraints, and at load time we need
to be able to enumerate the stored modules and all versions in order to
resolve them.

While the local storage key will be derived from the source and version,
that information is lost once it's hashed. While the entire storage
layer could be replaced to encode the needed data in the path itself,
this provides a minimal change to work with the existing storage code.

James Bardin 0962792257 surface registry errors to the user
Now that we can enforce local modules being relative or absolute paths,
we can be assured that any module source matching a registry pattern
must be found in the registry. This allows us to surface more useful
errors to the user, rather than simply stating that a source string
isn't valid.

must be a registry module.

James Bardin cb0e37a870 implement provider inheritence during loading
This implements provider inheritance during config loading, rather than
during graph evaluation. At this point it's much simpler to find the
desired configuration, and once all providers are declared, all the
inheritance code in the graph can be removed.

The inheritance is dome by simply copying the RawConfig from the parent
ProviderConfig into the module. Since this happens before any
evaluation, we record the original interpolation scope in the
ProviderConfig so that it can be properly resolved later on.

Some of them remain private within the config package since they depend
on some other symbols in the config package, and they are not needed

Previously we were using fmt.Sprintf and thus forcing the stringification

containing potentially-multiple errors and possibly warnings.

Martin Atkins b91bd62747 config/configschema: Sensitive flag for attributes
We don't currently have any need for this information, but we're
propagating it out of helper/schema here pre-emptively so that once we
later have a use for it we will not need to rebuild the providers to gain
access to it.

The long-term expected use-case for this is to have Terraform Core use
static analysis techniques to trace the path of sensitive data through
interpolations so that intermediate results can be flagged as sensitive
too, but we have a lot more work to do before such a thing would actually
be possible.

Martin Atkins 0ef985cada config/configschema: Block.ImpliedType delegates to zcldec
zcldec now has its own function for computing the implied type for a spec,
so we can use that instead of our own logic.

The zcldec logic is more general since its spec model is more general than
our schema model here, but it produces the same results for the subset
of specifications that our DecoderSpec method produces.

Martin Atkins b851fa71c9 config: Make HIL-based functions available to HCL2 via a shim
Terraform has a _lot_ of functions written against HIL's function API, and
we're not ready to rewrite them all yet, so instead we shim the HIL
function API to conform to the HCL2 (really: cty) function API and thus
allow most of our existing functions to work as expected when called from
HCL2-based config files.

Not all of the functions can be fully shimmed in this way due to depending
on HIL implementation details that we can't mimic through the HCL2 API.
We don't attempt to address that yet, and instead just let them fail when
called. We will eventually address this by using first-class HCL2
functions for these few cases, thus avoiding the HIL API altogether where
we need to. (The methodology for that is already illustrated here in the
provision of jsonencode and jsondecode functions that are HCL2-native.)

Martin Atkins bbf9725134 config: Validate resource "count" for HCL2-specified resources
This early validation uses interpolation of a placeholder value to achieve
some "best effort" validation of the validity of the count attribute.
Since HCL2-specified resources can't be interpolated using the main
interpolator, here we branch and use the HCL2 API to do a
largely-equivalent (though slightly less accurate) check.

In the long run we don't really need this extra check at all, since the
validation walk does a more accurate version of the same thing. However,
we're preserving this for now in the interests of minimizing the amount
of change for the main codepath during our experiment.

Martin Atkins 71e68f06c4 config: allow tests to force using the HCL2 loader
Currently the default for tests is to use the old HCL loader, but we need
to be able to test aspects of the new loader as we work through the
experimental phase. This new function testConfigHCL2 is the same as
testConfig except that it forces the use of HCL2 even if the opt-in
comment isn't present, thus allowing us to implement tests that ensure
that the exact same file works in both the old and new cases.

Once the HCL2 loader becomes the default this function will be removed
and callers will start calling into the normal testConfig function.
2017-10-03 17:47:01 -07:00
Martin Atkins d91327eaa0 config: allow HCL2 experiment opt-in (build-time flag to enable)
Use the new HCL2 config loader when the opt-in comment #terraform:hcl2 is
present in a .tf file.

For now this is disabled for "normal" builds and enabled only if
explicitly configured via a linker flag during build. This is because it's
not yet in a good state to be released: the HCL2 loader produces RawConfig
objects that the validator and interpolator can't yet deal with, and so
using HCL2 for anything non-trivial currently causes Terraform to crash
in real use.
2017-10-03 17:47:01 -07:00
Martin Atkins b0215fcd0f config: HCL2 config loader
This loader uses the HCL2 parser and decoder to process a config file,
and then transforms the result into the same shape as would be produced
by the HCL config loader.

To avoid making changes to the existing config structures (which are
depended on across much of the codebase) we first decode into a set of
HCL2-tailored structs and then process them into the public-facing structs
that a loader is expected to return. This is a compromise to keep the
config package API broadly unchanged for now. Once we're ready to remove
the old HCL loader (which implies that we're ready to support HCL2
natively elsewhere in the codebase) we will be able to simplify this
quite considerably.

Due to some mismatches of abstraction between HCL/HIL and HCL2, some
shimming is required to get the required result.

Martin Atkins edbbe41b44 config: allow a HCL2 body to piggy-back on a RawConfig
At this time we're not ready to refactor the various uses of RawConfig

RawConfig object that we can then recognize and unpack once this object
is returned to us in an interpolation call.

James Bardin f6e89bb8c3 record the subdirectory in the FolderStorage
Module detection currently requires calling the registry to determine
the subdirectory. Since we're not directly accessing the subdirectory
through FolderStorage, and now handling it within terraform so modules can
reference sibling paths, we need to call out to the registry every
time we load a configuration to verify the subdirectory for the module,
which is returned during the Detect.

Record the subdirectories for each module in the top-level of the
FolderStorage path for retrieval during Tree.Load. This lets us bypass
Detection altogether, modules can be loaded without redetecting.

James Bardin 6c20141c30 remove subdir handling from Tree.Load
Terraform was redundantly handling `//dir` notation which should be

as expected, the subdir was stripped off and accessed through the module
configuration.

This scheme will no longer works now that go-getter supports `*`
subdirectories
    (e.g. `//*` would be analogous to `tar --strip-components=1`).

Even though this allows Terraform to use go-getter's native unpacking,
detection is still done separately because Detect requires a `pwd` which
is dependent on the configuration directory and not known to the
global FolderStorage.

Martin Atkins f70318097a config: fix provider version constraint validation
Previously we were using the "semver" library to parse version
constraints, but we switched over to go-version and encapsulated it
inside our own plugin/discovery package to reduce dependency sprawl in
the code.

This particular situation was missed when updating references to the new
path, which meant that our validation code disagreed with the rest of
the code about what is considered a valid version constraint string.
By using the correct function, we ensure that we catch early any invalid
versions.

Previously the logic for inferring a provider type from a resource name
was buried a utility function in the 'terraform' package. Instead here we
lift it up into the 'config' package where we can make broader use of it
and where it's easier to discover.

Martin Atkins 73fc9985b2 config: add "version" argument to provider blocks, disabled
In future we will support version constraints on providers, so we're
reserving this attribute name that is currently not used by any builtin
providers.

For now using this will produce an error, since the rest of Terraform
(outside of the config parser) doesn't currently have this notion and we
don't want people to start trying to use it until its behavior is fully
defined and implemented.

It may be used by third-party providers, so this is a breaking change
worth warning about in CHANGELOG but one whose impact should be small.
Any third-party providers using this name should migrate to using a new
attribute name instead moving forward.

Martin Atkins 410b60cb7f Stop requiring multi-vars (splats) to be in array brackets
Prior to Terraform 0.7, lists in Terraform were just a shallow abstraction
on top of strings with a magic delimiter between items. Wrapping a single
string in brackets in the configuration was Terraform's prompt that it
needed to split the string on that delimiter during interpolation.

In 0.7, when first-class lists were added, this convention was preserved
by flattening lists-of-lists by one level when they were encountered in
configuration. However, there was an oversight in that change where it
did not correctly handle the case where the inner list was unknown.

In #14135 we removed some code that was flattening partially-unknown lists
into fully-unknown (untyped) values. This inadvertently exposed the missed
case from the previous paragraph, causing issues for list-wrapped splat
expressions with unknown members. While this worked fine for resources,
due to some fixup done inside helper/schema, this did not work for other
interpolation contexts such as module blocks.

Various attempts to fix this up and restore the flattening behavior
selectively were unsuccessful, due to a proliferation of assumptions all
over the core code that would be too risky to change just to fix this bug.

This change, then, takes the different approach of removing the
requirement that splats be presented inside list brackets. This
requirement didn't make much sense anymore anyway, since no other
list-returning expression had this constraint and so the rest of Terraform
was already successfully dealing with both cases.

This leaves us with two different scenarios:

- For resource arguments, existing normalization code in helper/schema
  does its own flattening that preserves compatibility with the common
  practice of using bracketed splats. This change proves this with a test
  within the "test" provider that exercises the whole Terraform core and
  helper/schema stack that assigns bracketed splats to list and set
  attributes.

- For arguments in other blocks, such as in module callsites, the
  interpolator's own flattening behavior applies to known lists,
  preserving compatibility with configurations from before
  partially-computed splats were possible, but those wishing to use
  partially-computed splats are required to drop the surrounding brackets.
  This is less concerning because this scenario was introduced only in
  0.9.5, so the scope for breakage is limited to those who adopted this
  new feature quickly after upgrading.

As of this commit, the recommendation is to stop using brackets around
splats but the old form continues to be supported for backward
compatibility. In a future _major_ version of Terraform we will probably
phase out this legacy form to improve consistency, but for now both
forms are acceptable at the expense of some (pre-existing) weird behavior
when _actual_ lists-of-lists are used.

This addresses #14521 by officially adopting the suggested workaround of
dropping the brackets around the splat. However, it doesn't yet allow
passing of a partially-unknown list between modules: that still violates
assumptions in Terraform's core, so for the moment partially-unknown lists
work only within a _single_ interpolation expression, and cannot be
passed around between expressions. Until more holistic work is done to
improve Terraform's type handling, passing a partially-unknown splat
through to a module will result in a fully-unknown list emerging on
the other side, just as was the case before #14135; this change just
addresses the fact that this was failing with an error in 0.9.5.

Martin Atkins 81b0c4b28d config: generate errors for unnamed blocks of various sources
We've been incorrectly validating (or not validating at all) the
requirement that certain blocks be followed by a name string, to prohibit
e.g. this:

    variable {}

and:

    variable = ""

Before this change we were catching this for most constructs only if
there were no _valid_ blocks of the same name in the same file. For
modules in particular, we were not catching this at all.

Now we detect this for all kinds of block (resources had a pre-existing
check, so aren't touched here) and produce a different error message
depending on which of the above incorrect forms are used.

This fixes #13575.
